GRAIN WEIGHING AND REGlSTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 346,272, dated July 27, 1886.

Application died October 26, 1885.

T0 (tZZ whom it may concern.-

Be it known that I, Wimnan 1t. DUXKEL, a resident ofMacon, county of lllacon, and State of Illinois, have invented certain new and useful Improvementsin Mechanism for Determiniug and Registering the \Veight of Grain, of which the following is a specification.

My invention consists in certain details of construction and combinations of parts, as hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 is a perspective view of my machine. Fig. 2 is a side elevation of the weighing device, representing the side opposed to that shown in Fig. 1. Fig. 3 is a vertical section of the weighing device. Fig. 4; is an elevation of a side of the elevatorcasing. Fig. 5 is an interior face view of the internal arrangement of the registering mechanism. Fig. 6 is an edge view of the same, and Fig. 7 shows the graduated dial-face and indieating-pointers.

a is the casing for the weighing mechanism.

Z) is the registering device.

0 is a weighted lever that forms a part of the weighing mechanism.

(1 is a horizontal conveyor having a rotating screw.

6 is the upper and '2' thclowcr portion of the grain-elevator.

f and a are chain belts.

/L is a triangular portion of the elevator, that swings into the position indicated by dotted lines in Fig. 4, to permit the upper part, 0, to be laid in a horizontal positiom 7c is a horizontal conveyer provided with a drag-belt, and adapted to be hinged to the top of a grain-separator.

Z Z represent hinges on conveyor 7.:.

m is a short chute that receives the grain from the separa-tor-discharge.

n is a scalebeam pivoted on casing a.

p is ablock on an end ofthe shaft of the grainweighing receptacles.

q are anti-friction rollers in the corners of block 1).

r, Fig. 3, are radial partitions that divide the weighing-receptacle into quadrantal compartments.

s are stops on said partitions. that Jo-oper- Serial No. 180,920. (No model.)

ate with trip-plate to stop the rotation of the receptacle.

tis a trip-plate, that, actuated by the falling grain, assumes the position indicated by the dotted lines and stops the motion ofthe weigln ing device at every discharge thereof.

1), Figs. 5 and 6, shows a gear-wheel that receives motion through pinion I) from the axle of the rotating graiirreceptaclcs.

If is a tooth rigid with wheel Z) on the under side thereof.

b is a broad-faced pinion that receives motion from tooth If and imparts the same to wheel 6 b is a tooth that imparts motion to Z)".

\Vheels Z), b and I) rotate independcntl y of each other, and are provided with indicatingpointers bl, I), and 1), respectively.

I) and I)" are pawls that operate on wheels If and I), to prevent desultory motion therein.

The grain is received by chute m, which is connected with the discharge of the separator. Buckets in elevator c convey said grain to screw-conveyor (Z, and said screw-conveyor discharges into weighing device a. The receptacle is held in the position indicated in Fig. 3 by the pressure of the scale-beam against block 1), and when a sufficient amount of grain has accumulated in a compartment to overbalance the scale-beam, then a discharge will be effected by a quarter-revolution of the said. receptacle. \Veighted arm 0 holds trip-plate t horizontally across the discharge-spout of the grain-weighing device, and at each and every discharge of the receptacle the weight of the grain carries said plate into the position indicated by the dotted lines, thereby locking the receptacle, as shown. After an absolute stop has been effected by the trip-plate, above described, the weighted arm 0 causes said plate to assume its original position preparatory to another discharge. The grain falls from the weighing mechanism onto a drag-belt in con vcycr 7.:, and may be discharged from either end thereof, according to the direction given to the motion of the belt.

The mechanism preferred for the purpose of shifting the direction of the drag-belt is shown in Fig. 4, and consists .in a combined sprocketwheel and gear-pulley, s, on. an oscillating lower part of the elevator, is hinged to the top of a grain-separator when in operation, and to enable the same to be laid down when not in use portion h, of a triangular form, is made detachable, as indicated.

The rotation of wheel I) is intermittently rotary in one direction, and its complete rotation consists in ten forward movements. Ten rotations of wheel 0 produce one rotation in wheel b tooth I) and pinion I) being directly instrumental in effecting this result. Tooth b on wheel 1) produces a revolution in wheel b for every ten revolutions in wheel I), and as a result of the complete arrangement pointer I) of wheel b indicates units on the dial-plate, pointer b of wheel indicates tens, and pointer if of wheel 11 indicates hundreds, thus making a register of any number less than one thousand readily practicable.

As represented in the drawings, the register indicates seven hundred and forty-two, b in dieating the seven hundred, I) the forty, and b the two.

'I claim as new and desire to secure by Letters Patent-- 1. The combination, in automatic grain-meters, of quadrantal compartments on a horizontal shaft, a block on said shaft square in vertical outline, aweighted scale-beam having its power end resting against the under side of said block, and a trip-plate located under the grain-discharge and pivoted to impinge against the rotating partitions, as set forth.

2. Casing a of grain-weighing mechanism, elevator e z, having removable portion 71, upper conveyer, d, and lower conveyor, k, all constructed and arranged to operate as set forth.

3. In a registering device for grain-weighing mechanism, the combination oftoothed wheel I), having lateral tooth b double-faced pinion I), having lateral tooth If, wheel I)", in mesh with pinion I), and wheel b, adapted to be operated bytooth b, the said wheels I), b, and b being respectively provided with indicating-pointers b, b, and b, as set forth.
